The BX312 has a fiberglass filled nylon handle and a thumb perch with deep thumb grooves for excellent grip control. A partially serrated 7Cr17 stainless steel blade is easy to sharpen and holds a great cutting edge. A deep carry pocket clip makes it easy to carry on the job when you need it most. A thumb hole in the blade makes one-handed opening easy; right or left handed. Backed by Coast's lifetime guarantee against defects in materials and workmanship.
